<pre wrap="">That was enough for me. Don't even remember who explained it, but it was around the famous entry of .CS into the root zone that created the "interesting" situation with CS.BERKELEY.EDU (and others) and massive weird extra hacking in sendmail.cf due to the Janet "reverse" order of labels in a domain name.</pre>

It is indeed funny. There were several routes out of the UK that one
needed to route specifically. UCL's NSS gateway (UK.AC.UCL.CS.NSS
then UK.AC.NSFNET-RELAY or Rutherford Appleton Labs BITNET gateway
UK.AC.RL.IB then UK.AC.EARN-RELAY and these needed to swap the
address over. The relays got confused, as they would sometimes swap
the DNS addresses over and sometimes not. Of particular interest was
cs.net.<br>
